[TowerTalk] US Tubular tower

[Richard D. Markel]

I must use a tubular tower in my location.

I plan on installing a 55 foot US MA 550 tower with motor pull-down 
drive.  I have tentatively decided on a Steppir two element beam (specs 
aren't too shabby for such a short boom) either bolted directly to the end 
of the top section of the tower or only 6 inches above the tower on the 
mast.  The mast itself would have a total length of 10 feet with about 
seven feet protruding above the tower.  At the top of the mast would be an 
Optibeam 40 meter rotatable dipole.  Total wind load would be about 7.5 
feet with a total weight (not including mast) of about 50 lbs.

How does this sound?  Is the MA 550 up to it?  I think this is the best I 
can do at this location and still get a forty meter antenna up at 
acceptable height.

Your thoughts would be appreciated.

Tnx
